I'm sure I read about this, possibly the release notes or faq. Cant find it right now, but I did find a post on devworks:
https://www.ibm.com/developerworks/community/forums/html/threadTopic?id=00104bb5-acf5-4036-93ba-29ea7b1d43b7 So sounds like you need a higher gpfs version, or possibly a rhel patch.

It appears that systemd is un-mounting the file system immediately after it is mounted. #strace of systemd shows that the device is not there. Systemd sees that the path is failed and umounts the device. Our only work around currently is to link /usr/bin/umount to true. Then the device stays mounted. 1 stat("/dev/aggr3", {st_mode=S_IFBLK|0644, st_rdev=makedev(239, 235), ...}) = 0 1 readlink("/sys/dev/block/239:235", 0x7ffdb657a750, 1024) = -1 ENOENT (No such file or directory) 1 stat("/sys/dev/block/239:235", 0x7ffdb657a2c0) = -1 ENOENT (No such file or directory) 1 socket(PF_LOCAL, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 19 # It appears that the major min numbers have been changed [root@gennsd4 system]# ls -l /sys/dev/block/|grep 239 lrwxrwxrwx 1 root root 0 Nov 19 15:04 253:239 -> ../../devices/virtual/block/dm-239 [root@gennsd4 system]# ls -l /dev/aggr3 brw-r--r-- 1 root root 239, 235 Nov 19 15:06 /dev/aggr3 [root@gennsd4 system]# ls /sys/dev/block/239:235 ls: cannot access /sys/dev/block/239:235: No such file or directory [root@gennsd4 system]# rpm -qa | grep gpfs gpfs.gpl-4.1.0-7.noarch gpfs.gskit-8.0.50-32.x86_64 gpfs.msg.en_US-4.1.0-7.noarch gpfs.docs-4.1.0-7.noarch gpfs.base-4.1.0-7.x86_64 gpfs.gplbin-3.10.0-229.14.1.el7.x86_64-4.1.0-7.x86_64 gpfs.ext-4.1.0-7.x86_64 [root@gennsd4 system]# rpm -qa | grep systemd systemd-sysv-219-19.el7.x86_64 systemd-libs-219-19.el7.x86_64 systemd-219-19.el7.x86_64 systemd-python-219-19.el7.x86_64 any help would be appreciated.
